Sweat wicking, our Force™ high-visibility short-sleeve Class 2 t-shirt makes short work of hot days. Built of 4.25-ounce, 100% polyester bird’s-eye knit, the Carhartt 100495BT Force fabric not only wicks moisture for a drier work day, but also releases jobsite stains and grime.˜It also features 3M™ Scotchlite™ Reflective Material-5510 Segmented Home Wash Trim which is segmented for superior breathability and durability plus an enhanced range of motion. In addition, it maintains its performance through 75 home launderings. The shirt includes a rib-knit crewneck collar for comfort, plus a tagless neck label to eliminate chafing. Side-seamed construction minimizes twisting.
